Abstract
A method and apparatus for setting an internal register of an integrated circuit (IC) via a multiplexed pin which also passes an RF signal is provided. An internal RF signal path couples the pin to an internal terminal for the RF signal, and a register setting signal path couples the pin to an internal register. The internal register may be an address register, such as a USID address register of a MIPI RFFE bus. A capacitor on the RF signal path may block the constant voltage, and a resistor or inductor on the register setting signal path may block the RF signal. The integrated circuit may include an RF section and a controller section, where the controller section may be used to control the RF section. The controller section is responsive to an address associated with the address register.
